The Vision G2 Classic 6 dissolution tester is a compact, rugged workhorse, precision engineered to ease the rigors of manual dissolution testing. The Vision G2 Elite 8 dissolution tester is a versatile performance machine, built with the highest quality components and engineering for automated dissolution testing. The CD14 Comparative Dissolution with 14 vessels allows testing of two different drugs at once. Teledyne Hanson’s Super Precision Vessel™ with its closer conformance to an ideal vessel shape provides more consistent vessel-to-vessel dissolution test results in USP Apparatus 2.

Available models

The Vision G2 Classic 6 dissolution tester is the compact, rugged workhorse sibling to the Vision G2 Elite 8. Named in honor of the world’s first dissolution tester, a six-position test station introduced by Hanson Research in 1969, the G2 Classic 6 is precision engineered to ease the rigors of manual dissolution testing. The G2 Classic 6 meets and exceeds worldwide standards including compliance with USP, FDA, ASTM, EP, JP, CE, CSA, RoHS, and 21 CFR Part 11.

Key features:

  • Award-winning design (2 across x 3 deep) provides easy access to all vessels
  • Compact footprint saves valuable bench space
  • 6-position Easi-Lock™ vessel plate ensures proper vessel centering
  • Up to 100 protocols stored (create, manage, call routines)
  • Superior coating protects vessel plate from corrosion
  • Fixed drive head guarantees repeatable, drive head positioning
  • No tools or adjustments needed to switch among USP App. 1, 2, 5, 6, and 150 mL and 250 mL small volumes
  • “Quick Test” feature begins tests immediately with the push of a button
  • Adaptable for automated sampling

The Vision G2 Elite 8 dissolution tester is a versatile performance machine, built with the highest quality components and engineering. The G2 Elite 8’s ergonomic design and workhorse performance make it ideal for automation and extended applications as well as for 8-sample manual testing. The G2 Elite 8 meets and exceeds worldwide standards including compliance with USP, US FDA, ASTM, EP, JP, CE, CSA, RoHS, and 21 CFR Part 11.

VISION G2 Dissolution Testing

Vision G2 dissolution testers are designed with over 60 years of dissolution expertise and know-how. The modular design is plug-and-play ready making these systems upgradeable or automated without the need for separate firmware. They come standard with a full color touchscreen and intuitive menus, giving users the confidence of precision control for speeds 25-250 rpm and temperature 25-55 °C. Powerful programming, backed by a robust security system for 25 users, features the ability to create up to 100 unique protocols that can be conveniently transferred by flash drive to other Vision G2 testers, resulting in higher throughput and sample analysis.

Key features:

  • Scalable design easily configured for automated, hands-free sampling

  • 8-position Easi-Lock™ vessel plate ensures proper vessel centering
  • Superior coating protects vessel plate from corrosion
  • Easi-Lift™ drive head with multi-lock positions allows for quick, repeatable position changes
  • No tools or adjustments needed to switch among USP App. 1, 2, 5, 6, and 150 mL and 250 mL small volumes
  • Can be configured for unattended automatic introduction of the dosage form when media has reached the user-specified temperature or time

  • “Quick Test” feature begins tests immediately with the push of a button
  • Optional Auto-Probes reduce hydrodynamic interference by automatically exiting the vessels after sampling, unlike stationary probes that remain in the vessel throughout the dissolution process

  • Minimal user adjustments with easy set up and go

The Teledyne Hanson 14-vessel CD14 Comparative Dissolution Tester runs two methods simultaneously or independently—ideal for bioequivalence studies of generic vs. innovator drug formulations. The 14 stirring positions allow for 6+1 or 12+2 configurations for improved workload efficiency in R&D, formulations, QC, and stability-test labs. With digital temperature probes at 12 positions the CD14 comparative dissolution tester is able to test two different formulations with separate settings for every parameter under the same temperature conditions.

Fast, powerful computer control

The CD14 is controlled by a fast, powerful computer built into the color touch screen display mounted to the drive head. The adjustable tilt angle accommodates operators of different heights while the Linux-based operating system with its own SQL database responds instantly to user input. The highly durable resistive touch screen works with gloves on or off. An easy-to-use interface includes context-sensitive help; logs for events, errors, test reports, test history, and service; rapid programming of new methods; ability to search database by any combination of fields; import/export including full system backup; programmable alarms for automatic power-on and warm-up; countdown to sampling points; tools including full system diagnostics; and more.

Key features:

  • The CD14 provides the smallest footprint in the 14-vessel class: 85 cm W x 61 cm D.
  • Precision vessel centering system exceeds the most demanding enhanced mechanical specifications.
  • Store up to 500 protocols (methods) on-board.
  • Run two different 6-vessel methods simultaneously or one 12-vessel method.
  • Rugged waterbath with low-position front port for ease of draining.
  • Heater/circulator slides out for ease of servicing.
  • Large color touch screen with adjustable tilt angle for operators of different heights.
  • Compatible with Apparatus 1, 2, 5, and 6.
  • Spindle speed: 25 rpm to 250 rpm, accurate to ± 1 rpm with displayed resolution 0.1 rpm.
  • Temperature: programmable from 25.0 °C to 50.0 °C with accuracy of ± 0.5 °C.
  • Digital temperature probes: 10 °C to 60 °C with accuracy of ± 0.1 °C from 30 °C to 55 °C, and displayed resolution of 0.01 °C.
  • Compliant with USP, EP, JP, US FDA Enhanced Mechanical Calibration and ASTM E2503 standards.
